Run your analysis now →Filing growth compares 2021 (101 records) with 2024 (81) — a three-year span. 2024 is the most recent year we treat as complete: publication lags filing by roughly 18 months, so 2025 onwards are still filling in and any growth rate that ends there would understate the field. Top-5 share is the combined record count of the five largest assignees divided by all 2,334 records in scope (CR5), not by the ranked leaders only.
Laser marking and traceability patents span the physics of how a beam alters a surface — annealing marks, contrast generation, corrosion resistance of the mark — and the data layer that makes the mark useful, from data matrix code generation to readability grading at speed. The scope here pulls records where both a marking method (laser marking, laser engraving, direct part marking) and a traceability or quality attribute (contrast, corrosion resistance, marking speed, readability grading) appear together, which keeps the set focused on marks meant to be read back reliably rather than purely decorative etching.
The set covers 2,334 published records filed or published between 2015 and mid-2026, drawn from a mix of medical device, packaging, industrial laser and automotive-component filers. Because publication trails filing by roughly 18 months, the most recent one to two years in any trend understate true filing activity.
Pick a task. Every answer cites the patents behind it.
Two views of the same 2,334-record set: how filing activity has moved year over year, and which technical branches carry the claim density.
Annual filings climbed to a peak of 188 records in 2019, then declined through the early 2020s; the complete-year comparison shows a 20% drop from 101 filings in 2021 to 81 in 2024. Readers should treat 2025 and 2026 figures as still filling in given the usual publication lag.
B41M (printing and marking processes) leads at 24.4% of the 2,334 records, with B23K (welding, soldering and brazing — where beam-material interaction claims sit) close behind at 23.8%. G06K (data recognition) at 17.9% marks the read-back layer, while B65D packaging, A61M body-fluid devices, C08K polymer additives and B29C plastics shaping each carry a smaller but distinct share, reflecting how many end industries this search string touches.
Shares are the percentage of the 2,334 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Try EurekaThis disclosure relates to methods and apparatuses for marking a data matrix code in the form of an n*m cell matrix of light and dark cells, which respectively consist of a light or dark s*t pixel matrix, on a workpiece by a laser beam, wherein a laser processing unit directs the laser beam onto the workpiece, scans, pixel row by pixel row, the workpiece region to be marked, respectively with a constant marking speed and alternately in opposite directions, and wherein the light pixels and/or the dark pixels are marked on the workpiece during the scan by temporarily switching on the laser beam.Filed by Trumpf Werkzeugmaschinen; published 2017-03-23.

The leader holds 154 records with the fifth-place assignee at 41 and tenth place at 24 — a steep drop-off after the top few. Below the top ten, the ranked field of 100 companies thins into single- and low-double-digit filers, which is where freedom-to-operate work usually needs the most care rather than the top of the table.
Filing activity peaked at 188 records in 2019 and has eased since, with the last fully comparable window showing a 20% decline from 101 to 81 records. That is a genuine slowdown in complete-year data, not a publication-lag artefact — though 2025-2026 counts will still rise as records publish.
The United States receives the largest single share of filings, followed by the European Patent Office and WIPO's PCT route, with China, Germany and Austria filling out the next tier. The PCT volume signals many filers are seeking multi-jurisdiction cover rather than filing nationally only.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to laser marking and traceability, with the prior art for and against each one.
The ranked field spans medical-device, packaging and industrial-laser assignees; recent-year momentum data shows several of the most active historical filers have gone quiet.
The top-ranked assignee holds more than three times the record count of the fifth-place filer (41), pointing to a company that treated laser marking and traceability as a core claim area rather than an incidental filing.
Recent-year momentum data shows multiple assignees among the most active historically — including filers with -100% year-on-year change — recording zero filings in the latest year. This does not necessarily mean exit; it may reflect the publication lag on very recent applications.
Only 10 co-assignee pairs appear in the dataset, and the strongest repeating pairs all involve the same lead assignee working with individual named inventors rather than joint corporate ventures — collaboration here looks more like internal inventor teams than cross-company alliances.

The dataset points to a few concrete next steps for teams deciding where to file or where to watch.
With the top ten holding only 24.0% of all 2,334 records, most claim density sits among single- and low-digit filers further down the ranking — a harder search than checking the leader alone.
Run a freedom-to-operate search in Eureka →Several historically active assignees show zero filings in the latest year; confirm whether that reflects publication lag or a genuine shift before assuming the space has opened up.
Track assignee momentum in Eureka →Corrosion resistance testing, readability grading automation and low-contrast decoding sit behind the core B41M/B23K claim mass and may offer clearer first-claim territory.
Explore white space in Eureka →The ranked field covers 100 assignees, with the leader holding 154 records and a steep drop to 41 at fifth place and 24 at tenth. The top five combined account for 17.5% of all 2,334 records in scope, and the top ten for 24.0% — a concentrated core followed by a long tail of low-volume filers. This is not a top-50 or top-100 cutoff; it is the entire ranking the dataset returns.
Filing peaked at 188 records in 2019 and has since cooled, with complete-year data showing a 20% decline from 101 filings in 2021 to 81 in 2024. Because publication lags filing by roughly 18 months, the 2025 and 2026 figures will rise as more records publish, but the 2021-2024 comparison already reflects a real slowdown rather than a lag artefact.
Marking process claims (IPC B41M) lead at 24.4% of the 2,334 records, closely followed by welding, soldering and brazing-related beam-material interaction claims (B23K) at 23.8%. Data recognition and presentation (G06K), covering the read-back side such as data matrix decoding, sits at 17.9%. Because a single record can carry multiple IPC classes, these shares add up to more than 100% and should be read as overlapping claim density, not as a breakdown of one whole.
Branches like corrosion resistance testing protocols for marks, automated readability grading and data matrix decoding under low-contrast conditions show comparatively thin filing relative to the dense core of marking-process and packaging claims. These sit adjacent to well-claimed territory rather than being wholly new, so a first claim there needs to be drafted carefully against the existing B41M and G06K prior art. Teams considering this space should run a targeted prior-art search before assuming the area is genuinely open.
US20170080734A1, filed by Trumpf Werkzeugmaschinen, covers a method and apparatus for marking a data matrix code as an n-by-m cell matrix on a workpiece using a laser beam scanned pixel row by pixel row at a constant marking speed, alternating direction between rows. It is a specific scanning-pattern and speed-control claim rather than a claim over data matrix marking in general, so it constrains particular row-scanning and speed-constancy implementations without necessarily blocking all laser data-matrix marking approaches. Anyone designing a similar system should check claim scope against alternative scan patterns or variable-speed marking, which may sit outside it.

Patent data carries inherent limitations: recent filings (typically the most recent 18–24 months) are under-counted due to standard publication lag; counts may be reported at either a patent-family or a patent-record basis and are not always directly comparable; classification, applicant-name, and citation data may contain errors, duplicates, or omissions; and the underlying search query defines and constrains the scope shown. As a result, the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
